Tax and Tip Calculator

You should always calculate your tip before sales tax is added (on the pre-tax subtotal). Sales tax is a government-mandated charge, not a direct service. Tipping standards dictate that server gratuity should reward the food and service quality alone, calculated strictly on the subtotal.

Tipping should always be calculated on the subtotal of the bill, before tax, shipping, or service fees are added. However, if you are using a coupon, voucher, or promotional discount, standard dining etiquette is to calculate the tip on the original, pre-discount subtotal, since the server performed the same amount of work.

Splitting tax and tip allows you to isolate the food and beverage subtotal from government fees. It keeps your tipping calculations transparent, saves you money by preventing you from tipping on tax, and helps you split bills with total clarity.
